We divide 12543154 by 135
The aim is to understand the frequency of 135 in 12543154.

Step 1:
1 divided by 135 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 135

Going ahead to step 2:
12 divided by 135 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 135

Moving on to step 3:
The number 135 fits into 125 0 times, leaving a remainder of 125.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 125 leaves us with 125.
Append the next digit (4) from the dividend to 125 and continue with: 1254 / 135

Advancing to step 4:
If we divide 1254 by 135, we get 9 and a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 1215 from 1254 to get 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 135

Step 5:
When dividing 393 by 135, we get 2 with a remainder of 123.
Write down 2 as next digit of the result. 
Result so far: 92.0
Subtract 270 from 393 to get 123.
Take the next digit (1) from the dividend and append it to 123, then repeat: 1231 / 135

Step 6:
When dividing 1231 by 135, we get 9 with a remainder of 16.
The next digit of our result is 9. 
Result so far: 929.0
If we take 1215 away from 1231, we end up with 16.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 135

Going ahead to step 7:
135 goes into 165 1 times with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 9291.0
Deduct 135 from 165 and we're left with 30.
Bring next digit (4) of the dividend behind the 30 and repeat the process: 304 / 135

Going ahead to step 8:
When dividing 304 by 135, we get 2 with a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 92912.0
Subtracting 270 from 304 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 9:
The number 135 fits into 340 2 times, leaving a remainder of 70.
The number 2 becomes the next digit in our result. 
Result so far: 92912.2
If we take 270 away from 340, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
135 can be fit into 700 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 92912.25
The remainder is 25 after subtracting 675 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 11:
If we divide 250 by 135, we get 1 and a remainder of 115.
Put 1 as the next digit of the answer. 
Result so far: 92912.251
Subtract 135 from 250 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 12:
When dividing 1150 by 135, we get 8 with a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 92912.2518
If we subtract 1080 from 1150, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 13:
If we divide 700 by 135, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 92912.25185
Subtracting 675 from 700 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 14:
250 divided by 135 is 1 with a remainder of 115.
Record the quotient 1 as the next digit in the result. 
Result so far: 92912.251851
Subtract 135 from 250 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 15:
135 goes into 1150 8 times with a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 92912.2518518
Deduct 1080 from 1150 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 16:
135 goes into 700 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 92912.25185185
If we take 675 away from 700, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 92912.25185185, and the remainder is 2.5e-08.
